Abstract: The fluidization of "coated particle" in high-temperature fluidized beds can be performed by different gas distribution systems. In this report the influence of different gas distribution systems is investigated on the circulating and resident time behaviour of the particlesin the 200 mm - model fluidized bed with the aid of the tracer technique. Hereby connections between fluidizing parameter and relative resident time of the particles in the fluidized bed are proved and the resident places and circulating frequences are shown by means of statistic analyses. For the determination of the best gas distribution systems with the most advantageous fluidization- and circulating conditions for the fabrication and isotropic and reproducible particle coatings comparative investigations have been carried out. These investigations show evident advantages of both gas distribution systems "single cone" and "porous plate" in contrary to other investigated concepts. With the aid of optimization investigations for the "single cone" constructional solutions are developed as well as instructions are given for the range of applications of the "porous plate".
